This paper presents analytical studies on the cyclic behavior of column-tree steel moment connections by FEA. The column-tree moment connections are composed shop welded beam-to-column connection and field bolted beam-to-beam splice. Two analytical model of column-tree moment connections were designed with beam splice lengths of 900mm and 1,100mm, which are roughly 1/6 and 1/7 of the span length of 7,500mm. In order to verify the FEA reliability, the analytical results was compared with experimental results. Meanwhile, the experimental results were understood better through analysis procedure.
